Problem: During flight, if the alternator failed, what would

immediately warn you of the problem? The voltmeter is by your feet, out of the normal scan area. The difference between a charging unit (@14V+-) and the battery 12V is @a needles width! Hard to notice while fully occupied piloting the helicopter.

 







Solution: Indicator (Idiot) Light

 

The red LED with leads and resistor was purchased from Auto
Zone. The mount was purchased from Radio Shack.



MODS 6:  

ALTERNATOR WARNING LIGHT

Another, better, alternative is this warning light from England. Available on E Bay for @$21.

The connection on the alternator is the "D" terminal. The downside of this installation is that it only indicates total failure of the alternator.
